The Hudson River Café may lack views of the titular river, it does have its own version of dramatic scenery. The large two-story patio gets buzz not only from its stylish Harlem clientele and live bands, but also from the occasional Amtrak train whizzing by mere feet away. The eclectic menu delves into oceanic eating--seviche, a raw bar and a lobster roll--and more earthbound fare like skirt steak with yucca fries and a half chicken with truffle mashed potatoes.
